The correct option is A Steroid hormones
Steroid hormones are crucial substances for the proper function of the body. They are synthesized and secreted into the bloodstream by endocrine glands such as the adrenal cortex and the gonads (ovary and testis). Steroid hormones are derived from cholesterol and are lipid-soluble molecules. Examples of steroid hormones synthesized by the adrenal glands are aldosterone, cortisol and androgens. Thus, the correct answer is option A.
